Ultra wideband bandpass filters with specified relative bandwidth
(Berlin : Walter de Gruyter GmbH, 2022)
Algorithm for the realization of the broad range of values of wide relative bandwidth (RBW) bandpass filter is introduced. Algorithm is based on periodic ideal cells each with short-ended stub. Theory is developed for a ...
The Application of Alumina for Electroanalytical Determination of Gallic Acid
(Springer, 2023)
A novel and simple electrochemical sensor for the determination of gallic acid is presented. The alumina sample was characterized by X-ray diffraction, FTIR, and particle size distribution analysis. The carbon paste electrode ...
Oscillatory carbonylation of poly(ethylene glycol)methyl ether acetylene. Improved model of reaction mechanism
(Springer, 2022)
The study presents a mathematical model of Bruk Temkin-Gorodsky Novakovic (BT-GN) reaction system employing palladium-catalyzed oscillatory carbonylation reaction of mono alkyne-terminated poly(ethylene glycol) methyl ...
Formation of niobium oxides by electrolysis from acidic aqueous solutions on glassy carbon
(Skopje, North Macedonia : Society of Chemists and Technologists of Macedonia, 2019)
In this study niobium oxide films were formed without peroxo-precursors from three different mixed acidic aqueous solutions on glassy carbon. Linear sweep voltammetry and potential step were techniques used for electrochemical ...
Novel composite based on zirconia and graphite. First results of application for synthetic dyes removal
(Universitatea Babes-Bolyai, Catedra de Filosofie Sistematica, 2022)
In this research composite based on zirconia and graphite was synthesized using the sol-gel method. Aim of this research is to activate and increase the photocatalytic activity of ZrO2 by combining with graphite-based ...
Chemical profile of Nepeta cataria L. var. citriodora (Becker) essential oil and in vitro evaluation of biological activities
(Lublin : Uniwersytetu Przyrodniczego Lublin, 2022)
Essential oil (EO) obtained by hydrodistillation in a Clevenger-type apparatus from aerial parts of Nepeta cataria L. var. citriodora (Becker), cultivated in Serbia was subjected to gas chromatography-mass spectroscopy ...
QSRR model for predicting retention indices of geraniol chemotype of Thymus serpyllum essential oil
(Taylor & Francis, 2020)
A total of 26 experimentally obtained retention indices on a logarithmic scale (log RI) from
Thymus serpyllum essential oil were used to build a robust predictive model. The selected descriptors were
used as inputs of ...
Supercapacitive properties of the alkali metal hydroxides-activated carbons obtained from sucrose / Суперкапацитативна својства угљеничних материјала добијених из сахарозе и активираних хидроксидима алкалних метала
(Belgrade : Serbian Chemical Society, 2022)
The influence of different hydroxides, applied to activate carbon black, on the electrochemical properties of activated carbon was investigated. The carbon material was prepared by hydrothermal treatment of sucrose and ...
Effect of temperature on mudstone disintegration process revealed with image analysis
(Springer Nature, 2022)
Quantifying rock weathering processes, especially in ways of nondisturbance and on-site investigation, is one of the most critical tasks in predicting rocks erosion rates and understanding the sediment transportation. We ...
Novel Solid-State Approach to Nickel Ferrite Electrocatalyst for the Detection of Gallic Acid
(Springer, 2022)
Nickel ferrite nanoparticles were synthesized via thermal decomposition of β-diketonato complexes of nickel(II) and iron(III). The mechano-chemical activation of the complex precursors was used to ensure the increase in ...
